' useful Improvements in Annunciator Systerms, of which the following is a specification. 7

This invention relates to improvements in annunciator systems and has particular application to a clock controlled annun ciator system for use in hotels, apartments and analogous places.

In carrying out the present invention, it is my'purpose to provide a system of the class described whereby a guest or guests in any room or number of rooms may be called automatically at any desired to predetermined time. I

It is also my purpose to provide an annunciator system for use in hotels and the like Places which will be entirely automatic in operation and which may be installed and maintained at a minimum expense.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forthdn and falling within the scope of the claims. .a

In the accompanying drawings; Figure 1 is a View in front elevation of a chronometer and associated arts of an annunciator system constructed 1n accordance with my present invention. Fig. 2 1s a view in end elevation thereof. Fig. 3 is a fragmentary vertical sectional view throu h the same. Fig. 4 is a horizontal sectiona view there through, parts bein shown in bottom plan.

Fig. 10 is an end elevation of the same. Fig. 11 is a view in side elevation of one of the plugs, parts being shown in section. Fig. 12 1s a fragmentary diagrammatic view showing the circuit connections between the chronometer and. a guest room. Fig. 13 is a diagram matic vlew showing the connections between the chronometer and switch board.

Referring now to the accompanying drawings in 'detail, A designates a switch board comprislng a base or table 1 of any suitable construction and a vertical slab or panel 2 upr sing from-the base 1 at the rear ed e o the latter and constructed of an suitab e material. Suitably secured to the ront face of the slab 2 are vertical strips 3 having the ad acent side ed es insulated one from another by strips 0 insulation 4: and caable of conducting an electric current. bedded in each conducting strip 3 are a plurallty of metallic jacks 5 arranged in a vertical row and suitably spaced apart and each electrically connected with the con ductln strip. In the present instance, I have s own the switch board as composed of forty-eight vertical conducting strips each equipped with fifteen jacks. Each jack is preferably although not necessarily, composed of a cylindrical metallic sleeve 5 stamped at diametrically opposite points to provlde inwardly projecting friction tongues 6 and having the outer ed e thereof flanged as at 7 and embedded within the respectlve strip on the switch board. Seated within recesses formed in the upper surface of the table 1 adjacent to the lower end of the slab or panel 2 are plugs 8 spaced apart longitudinally of the ta 1e, while secured to the under surface ofthe table top adjacent to each plug 8 is a metallic strip 9 equipped at one end with a binding post 10 and having the opposite end downturned as at 11 and formed with an eye designed-to receive one terminal of an electric current can" mg cord 12, the free terminal of the cord 12 bem fastened to the plug 8 as at 13. Suspen ed from each cord 12 by means of a sheave 14 is a weight 15 acting to hold the respective plug8 normally seated. In the embodiment of my invention selected 'for illustrative purposes,the plugs 8 are fifteen in number, corresponding with the number of jacks in each vertical strip of the switch board and such plugs are interchangeable with the jacks so that all of such plugs may be inserted within the jacks in one strip, if such is desired, or may be scattered over the panel.

Appropriatelyfastened to the up er edge of the panel 2 is a block 16 having tli edge thereof concaved and seated within the concavity in the block is a chronometer17 in the form of a clock, Inclosing the dial of the chronometer ooncentricall thereof is a metallic conducting ring 18, while surrounde upper ing the ring 18 is an annulus 19 composed of insulatin material, the ring 18 and the an-,

nulus 19 being embedded in theface of the chronometer. Pro ectin outwardly from the outer edge of the conducting ring 18 and spaced apart equal distances about such ring are pivot pins 20 upon each of which is fulcrumed between its ends a switch lever 21 having the outer end thereof overlying the insulated ring 19 and the inner end rounded otf as at 22 and disposed in the path of movement of the outer extremity of the spring finger 23 carried by one of the indicating hands of the chronometer, the hour hand in thepresent instance. In this form of m invention, one switch lever 20 is dispose adjacent to each hour mark while three switch levers are interposed between adjacent hour marks and spaced apart equal distances. For instance, one lever is dis: posed adjacent to the hour mark 12 on the dial of the clock while three levers are interposed between such hour mark and the hour 1, these last levers representing 15,

and 45 minutes after the hour 12. Embedded in the insulated ring 19 are contact pins 24 corresponding in number wit the switch levers and each disposed immediately adjacent to the outer end of one of such levers.

Arranged adjacent to the inner end of each switch lever is a stop pin 25 while fastened to each lever upon the inner side of the fulcrum point thereof is one extremity of, a coiled contractile spring '26 havin the other end thereof secured to the dia of the chronometer as at 27, such springs acting to maintain the levers normally out of engagement with the contact pins .24. These pins 24 and contact levers together with the conducting ring 18 constitute a circular series of switches arranged concentrically of the dial of the clock and corresponding in number to the number of conducting strips 3 0n the switch board and, as illustrated in Fig. 13, each contact pin 24 is wired up to one of the conducting strips 3 by means of a condictor 28. By means of this construction, it will be seen that as the hour hand of the clock moves over the face of the dial the switch levers will be actuated successively to engage the respective contact pins 24 thereby forming 'an electrical connection between the conducting ring 18 and the vertical strips on the switch board, the springs 26 restoring the switch levers to normal position succeeding the release of such levers by the finger 23 on the hour hand, it being understood that the finger 23 maintains each lever in engagement with the respective contact pin for an appreciable length of time.

Each binding post 10 electrically connected with a plu 8 is connected to one terminal of a conductor 29 leading to one side of an annunciator 30 located in a guests room or other similar place and from the opposite side of the annunciator leads a concase, the operator in charge of the switch board inserts the plug 8 connected with the annunciator in the particular guests room into one of the jacks in the circuit conducting strip 3 connected with the contact pin 24 in the path of movement of the central lever 21 of the three between the hours 6 and 7.

When the minutehand of the clock has moved to the proper position, the hour hand will be at a point a proximately centrally of the numerals 6 and 7 on the clock dial so that the finger 23 will contact with the inner end of the adjacent lever 21 and so swin the latter about its pivot in 20 whereby the outer end of the lever wi l engage the adj acent contact pin 24, thereby completing the contact circuit to the annunciator 30 in the respective guests room so that such respective annunciator will be energized, current flowin from one side of the battery 33 throug the common wire 34, the ring 18, pin 20, the particular lever 21, the contact pin 24 in engagement with such contact pin, the particular strip 3 on the switch board, plugged jack within such strip, the cord 12, connector 9, binding post 10, wire 29, annuncia-tor, conductor 31 and back to the other side'of the battery 33 by way of the respective conductor 32.

Should it be desired to call a number of guests at one time all of the plugs connected with the annunciators in the rooms of such guests are plugged into the jacks of the proper conductin strip on the switch board so that when t e hour hand of the clock has reached the desired point all of such annunciators will be sounded upon the operation of the particular switch lever.

From the foregoing description taken in connection with the accompanying drawings, the construction, mode of operation and manner of employing my invention will be readily apparent. It will be seen that I have provided an annunciator system for hotels, rooming houses and the like whereby any one or all of the guests in the hostelry may be called at any desired time.

While I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention.
